GroDev is a solo full-stack development studio founded by Dominik Groński in Poznań, Poland. Registered business (JDG) since May 2026, VAT ID PL7773109895.
We build custom web systems for businesses that need more than a template: CRM systems, booking platforms, client portals, e-commerce with custom checkout, and 3D product configurators powered by Three.js.
WHAT MAKES US DIFFERENT: • Solo senior developer — you talk directly to the person writing your code. No account managers, no juniors doing the actual work. • Client code ownership — your repository on your GitHub from day one. Zero SaaS lock-in. You can switch developers anytime. • Honest pricing — fixed brackets in writing before we start (no hidden "starting from"). Basic sites from PLN 1,500. Custom systems from PLN 15,000. • 30-day guarantee — bug fixes free after go-live. Longer support via SLA (MONITOR, CARE, PRIORITY packages).
FLAGSHIP EXPERTISE: 3D product configurators for manufacturers (furniture, windows, garages, fences, saunas, pools, pergolas). Real-time Three.js rendering in the browser, no plugins, works on mobile. Full alternative to Zakeke/Threekit (3-10x cheaper over 3 years).
FOR NEARSHORE CLIENTS (DE/AT/CH/UK): Polish developer rates 60-95 EUR/h — 40-60% cheaper than local DE/UK agencies with same senior quality. Cross-border invoicing (SEPA), reverse-charge VAT.

Dominik from GroDev is a power supply for Ustawnik.pl, a B2B portal for industrial suppliers. A WooCommerce-based store with a dedicated "contractor" role and a multi-brand catalog—SIA, Dynabrade, Bostik, Parker Lord, Obera, and Avatex—in a single currency.

The work was quick and efficient. Dominik led the project single-handedly, without any intermediaries – he responded to feedback promptly and implemented changes the same day.
